SPECIFICATION forming part of Letters Patent No. 686,382, dated November12, 1901. Application iilcd January 30, 1899. Renewed Mlarcli 14,` 1901.Serial No. 51,220. (No model.)`

To @ZZ whom, t may concern: l

Be it known that I, DANIEL CHARLES BECK, of the city of St. Louis, Stateof Missouri, have invented certain new and useful Improvements in Heel-Compressing Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to heel-compressing machines; and it consists ofthenovel construction, combination, and arrangement of parts hereinafterdescribed andclaimed.

Figure 1 is a side elevation of my improved heel-compressing machine.Fig. 2 is a front View thereof. Fig. 3 is a plan 'View of a rotatingdisk that carries the female portions of the dies. Fig. 4 is an enlargeddetail sectional View taken approximately on the line 4 4 of Fig. 2.Fig. 5 is an enlarged vertical sectional view .taken approximately onthe line 5 5 of Fig. l. Fig. 6 is a view of the under side of thecutter-head made use of in carrying out my invention. Fig. 7 is a planview of a heel, the same having been compressed in` my improved machine.Fig. 8 is a plan View of the upper forward end of the machine andshowing the vertically-operating carriage which carries the male die andthe cutter-head.

In the construction of my machine a suitable hollow standard 1 projectsupwardly from a base 2, and integral with and projecting laterally fromthe front side of the upper end of said standard 1 is a pair ofverticallyarranged ears 3, in which is mounted for vertical movement ablock 4. Passing longitudinally through the center of this block 4 is anaperture 5. l

The rear side of theupper end of the standard 1 is provided with aprojection 6, in which is fulcrumed a bell-crank 7, the horizontalportion thereof extending through the upper end of the standard 1 andinto the aperture 5 in the block 4. The forward end of this horizontalarm is provided with an antifriction-roller 8, which bears against thetop'and bottom walls of said aperture 5. The lower end of the Verticalarm of this bell-crank 7is bifurcated, and pivotally held in saidbifurcated lower end is an arm 9, the lower end of which carries anantifriction-rcller 10. A

,set-screw passes through an aperture formed through the rear wall ofthe lower end of the bell-crank 7 and into the upper end of the arm 9,and a second set-screw passes through 515 the rear wall of the lower endof the bellcrank 7 and bears against the rear side of the arm 9. Bymeans of these set-screws the arm 9 is adjusted backwardly andforwardly.

Located upon the base 2 and -to one side of 6o the standard 1 is a pairof alined standards 11, the upper ends of which are provided withbearings in which is rotatably arranged a longitudinal shaft 12, andupon said shaft immediately to the rear of .the standard 1 is 65 fixed adisk 13, upon the rear face of the edge of which disk is arranged atequal distances apart the eccentric lugs 14. The path of travel of theedge of this disk13 is in alinemeut with the center of the standard 1,and 7o during the rotation of said disk the roller 10 rides upon theedge of the face of said disk and upon the eccentric lugs 14. Anantifriction-roller 15 is journaled in thestandard 1 and bears againstthe rear side of the disk 75 13 immediately opposite the point againstwhich the roller 10 bears.

Fixed upon the shaft l2 a short distance to the rear of the disk 13 is aworm-wheel16,

the same being driven by a worm 17, that is 8ol carried upon the shaft18, which shaft is journaled in suitable bearings 19, that are fixed tothe base 2. This shaft 18 is the powershaft, and on one end thereof isfixed a belt- ,Wheel 20 and upon the opposite end is xed 85 a groovedpulley 2l.

Fixed to the front face of the verticallymoving block 4 is a pair ofrearwardly-projecting bars 22, on the front of the outer ends of whichis iixed a vertically-arranged slotted 9o block 23. Arranged forvertical movement in said slotted block 23 is a bar 24, the same beingvertically adjustable in the slotted block 23 by means of a hand-screw25, that passes upwardly through the top of the slotted block 23.Integral with the ends of the bar pulley 21.

located a pair of downwardly-projecting curved knives 30. Adjustablylocated in the lower one of the arms 26 is .a vertical rod 3l, with thelower end of which is formed integral a loop 32, that extends laterallyto a position immediately beneath the cutter-head 29. Fixed to andextending outwardly from the side of the lower end of the block 23 is anarm 33, upon the outer end of which is arranged for rotation a pair ofgrooved pulleys 34, the same being in horizontal alinement with thepulley 28. Extending laterally from the rear side of the projection 6 isan arm 35, upon the outer end of which is rotatably arranged a pair ofgrooved pulleys 37, the same being in vertical alinement with thegrooved A belt 38 passes around the grooved pulley 21, from thence toand over the pulleys 37, from thence forwardly around the pulleys 34,and finally around the pulley 28. Thus rotary motion is transmitted fromthe power-shaft 18 to the cutter-head 29.

Arranged upon opposite sides of the lower end of the block 4 is a pairof lugs 39, to which are hinged plates 40, the lower ends of which carrythe mating blocks 41, that form the male portion of the die of myimproved machine. These blocks 4l are provided on their opposite "sideswith the inclined faces 42, and the inside of each of said blocks isrecessed, as indicated by 43, the combined recesses being of the formrequired to give to the heel that is compressed. IThe upper meetingcorners of the blocks 41 are recessed to receive a head 44, which iscarried by a spring-actuated stem 45, that extends upwardly into theblock 4, the spring around this stem being an expansive coil-spring andacting to throw the blocks 41 outwardly when the block 4 is raised.Projecting forwardly from the center of the standard 1 is an extension46, to which is bolted a bearing 47. In said bearing is rotatablyarranged a vertical shaft 48, the same being vertically adjustable bymeans of the screw 49, passing through the lower end of the bearing 47.Formed on or fixed to the upper end of the shaft 4l is a disk 50, therebeing a beveled gear 5la formed integral with the under side of saiddisk 50. The top side of this disk 50 is provided with four circularlugs 51, in which are formed recesses 52 to receive the heels to becompressed, and which recessed lugs form the female members of the diemade use of in myimproved machine. A plurality of points 53 extendupwardly within the recessed lugs 51, and passing upwardly through thecenter of said lugs are the discharge pins or plungers 54. Formed in-theedge of the disk 50 immediately opposite the recessed lugs 51 are thenotches 55, into which notches engages the point 56 of the springbar 57,that is held in a block 58, located upon the side of the standard 1. Bymeans of this spring-bar and lug the disk 50 is held in proper positionwhen the male portion of the die is moving downwardly to compress theheel carried in the female portion of the die.

Rotatably arranged in the top of the outer end of the block 47 is aroller 59, against which the discharge pins or plungers 54 strike duringtheir travel around with the disk 50. Rotatably arranged in the upperend of the extension 46 is an ant-ifriction-roller 60, upon which theouter edge of the disk 50 rides; but the discharge pins or plun gers 54do not strike and ride over said roller during their travel with thedisk 50.

Rotatably arranged in the bearing 47 is a laterally-projecting shaft 61,upon which is fixed a beveled gear-wheel 62, the same meshing with thebeveled gear-wheel 51a, 'carried by the under side of the disk 50.Formed integral with the rear side of this gear-Wheel 62 is aratchet-Wheel 63, the same being provided with four notches, and looselyarranged upon the shaft 61, adjacent this ratchet 63, is an arm 64,which carries a spring-actuated pawl 65, the same engaging in thenotches of the ratchet-wheel 63. Fnlcrnmed upon the side of the standard1 is a-n arm 66, to the upper end of which is pivotally connected ahorizontally-arranged connecting-rod 67,the outer end of said rod beingadjustably held to the arm 64. The lower end of the arm 66 is pivotallyconnected to a rectangularly-bent bar 68, the same sliding horizontallythrough a lug 69, projecting laterally from the standard 1, and the freeend of this rectangularly-bent bar 68 carries an antifriction-roller 70,which rides directly upon the edge of the face of the disk 13 and uponthe eccentric lugs integral therewith. A retractile coil-spring 71 issecured to the lower end of the fulcrumed arm 66 and is for the purposeof returning said arm to its original position after it has been moved.

The operation is as follows: When power is applied to the shaft 18, theworm 17 thereon will impart rotary movement to the wormwheel16 and shaft12. Consequently the disk 13, which carries the eccentric lugs 14, willrotate. Rotary movement is also imparted to the shaft 27, carrying thecutter-head 29, by means of the belt 38, running over the variouspulleys. As the disk 13 rotates the eccentric lugs 14 will successivelypass beneath the roller and the rectangularly-bent .arm 68, whichcarries said roller, will be moved rearwardly in the direction indicatedby the arrow a, Fig. 1. This movement draws the lower end of the arm 66rearwardly and throws the upper end thereof forwardly, and consequentlythe connecting-rod 67 will be moved forwardly and the arm 64, carryingthe spring-actuated pawl 65, will be swung approximately one-quarter ofa revolution upon the shaft 61, and said spring-actuated pawl 65 willengage in one of the notches in the ratchet-wheel 63 and saidratchet-wheel and the beveled gear-wheel 62 will be moved onequarter ofa turn. The beveled gearwheel 62, meshing with the gear-wheel 51, willnecessarily move said gear-wheel 51 a quarter of a turn, and the disk50, carried by said gear- IOC IIO

En v d,

wheel 51, will move a corresponding distance. The single tooth 56,carried by the bar 57, will engage in one of the notches 55 in the diskD, and said disk will be held in position, with one of the female diesimmediately beneath the pair of blocks 41 and another one of the femaledies immediately beneath the cutter-head 29. The retractile coil-spring71 causes the connecting-rod 67, arm 66, and rectangularly-bent bar 68to return to their normal positions after passing over one of the lugs.The operator of the machine places the heels to be compressedsuccessively in the open female dies as they, are brought around by thecontinued rotation of the disk 50 and are successively carried beneaththe male portion of the die and then to a point beneath the cutterl1ead.The lugs 14 after riding beneath the antifriction wheel 70 pass beneaththe antifriction-wheel 10 and the lower end of the bell-crank 7 is movedoutwardly, and consequently the outer end of the horizontal arm of saidbell-crank carrying the block 5 is moved downwardly. Said block 5 movesdownwardly between the ears 3, and necessarily all of the mechanismcarried by said block moves downwardly at the same time. The inclinedfaces 42 of the blocks 41 strike against the inclined faces of therecesses in the female die 51, and as a result thereof the blocks 41move toward each other as they move downwardly to compress the heelcarried by the female die. At the same time the male die enters thefemale die to compress the heel, the loop 32, carried by the rod31,passes over the compressed heel that is carried in the female dieimmediately beneath the cutterhead,and as said cutter-head movesdownwardly to its lowermost limit of movement any portion of thecompressed heel that is too high will be cut away and removed by theknives 30, and thus all of the heels will be of the samecontour and ofthe same thickness. When the lug 14 passes from beneath the roller 10,the bell-crank 7 will reassume its normal position and the male die andthe cutter-head will be elevated. During the time said cutter-head andmale die are elevated the operation of rotating the disk 50 a quarter ofa turn takes place and the heel just compressed is brought into aposition beneath the cutter-head, and the compressed heel that was sooperated upon by the knives ofthe cutter-head will be discharged fromits position in the female die owing to the elevation of the pin orplunger 54 by the roller 59,as shown in Fig. 4. The points 53 assist inholding the heel in position within the female die while said heel isbeing compressed and while it is being engaged by the knives of thecutterhead. The cutter-head is adjusted vertically by manipulating thehand-wheel 35 and the elevation of the disk 50 is adjusted bymanipulating the screw 49.

A heelcompressing machine ofr my improved construction possessessuperior advantages in point of simplicity, durability, and

general efliciency, requires the attention of but a single operator,will compress a large number of heels in a given time, and all of saidheels will be of the same contour and thickness after having passedthrough the machine.

The heels are of course stacked by means of wooden pegs, so that thecutters may readily trim them without being injured during theoperation, and in Fig. 7 the wooden-pin openings are shown.
